300在西门子的PLC产品类里属于:中型PLC系统,适合的控制对象一般都在256点以上,1024点以下的编程软件不一样,具体编程语言编程思路都不一样!
1、S7-200系列用的STEP7-Micro/WIN软件;S7-300使用的是STEP7软件。
2、S7-200系列的编程语言有三种:语句表(STL)、梯形图(LAD)、功能块图(FBD);S7-300系列的除了这三种外,还有结构化控制语言(SCL)和图形语言(S7 graph),其中SCL就是一种高级语言,高级语言可以更加方便的解决客户的专有问题,提高了程序执行效率,缩短了程序执行时间。
3、S7-300软件的特点就是提供了一些数据块来对应每一个功能块(Function Block-FB),称之为Instance。S7-300不能随意的自定义Organization Block、sub-routine和Interrupt routine,系统只能调用它OB1,其它的用FB-Function Block和FC-Function方式编辑,其它的也是预定义成了系统的了,System的S给它们(SFB、SFC)定义了自己的身份。
